CONTAINER.

Application filed August 27,1927. Serial No. 315,799.

This invention relates in general to con tainers and more particularly to a pail especially designed for use with lacquers, although possessing wide adaptability and capacity for advantageous use.

Pails or containers for lacquer are required to have closures for their discharge openings, which have liquid-tight seals with the parts of the pai'l with which they co-act, and the pail and closure structure, as well as the seal, must be appropriately rugged and strong to withstand severe usage and handling to which, they are subjected. Such containers will not be accepted for shipment unless they can withstand the so-called drop test. Moreover, lacquer is used in a great many instances in air guns of the type in which the lacquer is poured into a small cup attached to the gun, and filling these air guns from a pail of conventional size re-.

' quires provision of suitable pouring means. The problem is further complicated by the factthat lacquer must be stirred thoroughlybefore being used. In order to facilitate pouring, it has been the custom to use cans having restricted discharge necks, which are comparatively easy to seal and which facilitate pouring to some extent, but which make thorough stirring of the lacquer very dif-' ficult. Moreover, these cans must be boxed or crated for shipment as they are not adapted to withstand the rough usage. Heretofore a practical pail construction adapted to meet the various requirements of a container for lacquer or the like has not been available.

One of the principal objects of the invention is to provide a pail construction designed and adaptedfor use in shipping and dispensing lacquer.

Another object is to provide a pail construction of this character which'is of simple yet strong and rugged construction, so as to be well adapted to withstand rough usage of actual conditions, as well as the socalled drop test and which, while providing a strong and liquid-tight seal for its closure, nevertheless facilitates the thorough stirring of the lacquer and further provides for easy and controlled pouring of the lacquer into the air guns or other similar receptacle without spilling orsplashing of the lacquer.

A further object is to provide pail construction having these advantages and capacities and which embodies a suitable,

rolled and reinforced edge 3.

coated steel construction, so as to combine strength with a capacity to resist the attack of the solvents of the lacquer, thereby maintaining the structural integrity of the pail and avoiding impairment of the color or properties of the lacquer.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming a part of this specification, and in which:

Figure 1 is a view in diametrical vertical section showing the pail embodying the present invention;

Figure 2 is a plan view of such a pail with the coveror closure removed; and

Figure 3 is a fragmentary sectional view, similar to Figure l, but showing a slightly modified construction.

Referring-to the drawing, numeral 1 des ignates the body portion of the pail, which has a general form of a cylinder and is provided with a bottom 2. The upper end of the body of the pail is open and is )rovided' with a rounded rim, or flange, 3, laving a A closure or cover 4 is provided for the upper open end of the container and this cover is held in position on the container by means of lugs 5, which are bent up under the rim 3, as illustrated by. the dotted line in Figure 3. These lugs serve to clamp the flange 4 of the cover forcibly against the gasket'6 interposed between the flange 4* and a seat provided for the gasket on the rim 3, thereby affording very strong and rigid connection between the cover and the pail, as well as a liquid-tight joint. Hooks 5 on the lugs 5 facilitate the withdrawal of the lugs and the removal of the cover 4. The construction as thus far described is more clearly and fully set out in my (Lo-pending appli-. cation, Serial No. 134198, filed September 13, 1926, for container, and reference is made to such application for a detailed disclosureof these features. It isto be noted that the cover plate 4 has its body portion 4* inset into the open top of the container slightly.

With the container structure so far described when thecover plate 4 is removed, the contents of the pail are readily accessible for stirring, but serious difficulty is encounpensin tered when it is necessary, as it often is, to

pour the lacquer or other material in the pail into a small receptable, such as an air gun cup and the like. The present invention provides for controlled and easy pouring without danger of spilling or splashing and does this without interfering with the free and thorough stirring of the contents of the pail. For this purpose a flat pouring breast 6 is provided and is positioned just below the body 4 of the cover. Preferably this pouring breast consists of a flat metal plate of suitable form. In the embodii'nent shown the plate 6 is of segmental form and while this form has advantages, changes in the shape of plate 6 are contemplated. Around its curved edge plate 6 is provided with a I depending flange 7 which engages the neck of the pail and is spot-welded or otherwise secured thereto. At a point contiguous with the neck of the pail, the pouring breast is provided with a discharge opening or port 8. The free edge of the pouring breast may be ribbed as at 9 to stiffen and strengthen it.

With this construction a large and unobstructed opening remains at the upper open end of the pail to provide for thorough and easy stirring and yet, when it is desirableto pour the contents of the pail into a small container this may readily be done, as the pouring breast restricts the discharge of the contents to a small and well defined stream which clears the rim of the pail and does not splash or scatter. In disthe contents of the pail, the pail is lifted y its bail handle and the flange of its bottom is grasped, to tilt the pail so as to lower the portion thereof adjacent to discharge outlet 8. The pouring breast prevents the contents of the pail from spilling and spreading over the rim and down the outside of the pail and constrains the discharging contents thereof to a controlled and well defined stream which issues from the outlet 8.

The form the invention shown in Figure 3 is identical witlrthat just described, except as to the manner of mounting the pouring breast on the pail. In Figure 3 the pouring breast is designated at 15 and has a discharge outlet 16. The curved edge of the pouring breast is provided with an upwardly directed marginal flange-17 ofsubstantially inverted U-shaped cross section. The flange 17 snugly embraces the rim 3 of the pail and has an extremity 18 bent around the .rolled edge of the rim 3 to lock the-pouring breast 15 in position. This arrangement does not interfere with the application and removal of the cover, and the application and removal of the cover does not disturb the mounting of the pouring breast. The shape, position, extent and general characteristics of the opening 8, especially as shown in Figures 1 and 2, promotes the forsolvents of the lacquer.

mation of a well defined and concentrated stream and tends to avoid spilling or scattering.

In order to give the pail the strength and durability required, the pail itself and its cover are constructed of sheet steel of suitable gauge. The desirability of utilizing sheet steelhas long been recognized, but it has not been possible to use it heretofore for the reason that the steel is attacked by the This not only impairs the stcel to some extent, but, what is more important, it discolors the lacquer and otherwise injuriously affects the properties of the lacquer. In applicants construction this difliculty has been overcome by applying a thin and permanentcoating on the steel which makes it effective to resist the action of the lacquer solvents or other lac quer ingredients. This coating consists of an alloy of lead and tin, there being about 93 parts of lead to 7 parts of tin. These two metals are mixed and heated to prepare a molten bath into which the pails and covers are dipped. The lead is comparatively inexpensive and is entirely resistant to the reaction of the solvents or other ingredients of the lacquer, but, of itself, it does not have the capacity to adhere as a continuous and uniform coating of the sheet steel. This deficiency in the adaptability of the lead is entirely remedied by an addition of a small amount of tin, which co-acts with the lead to provide a coating-which easily adheres to the sheet steel and which penetrates and coats as well as seals all crevices or the like. The coating is indicated by a heavy line in drawing and is designated at C. It is to be understood that the proportions of lead and tin may be somewhat varied, but, in order to preserve the advantage of low cost, it is to utilize a relatively small amount of tin in a relatively large amount of lead.

Pails or,containers embodying the present invention are usually constructed with a lengthwise seam, which must be welded to be liquid-tight. Drawing a single-piece pail is not a commercial possibility, due to the expense involved, but even were the pail drawn from a single piece, the drawing would have to be carried out in a succession of drawing operations, with annealing between eachdrawing operation. The welding in the one instance and the annealing in the other makes it necessary to first completely construct the pail liquid-tight and afterwards to coat itwith the lacquer resisting material. Tin-plate or terncplate, that is, previously coated sheet steel, could not be used successfully because the welding or annealing would remove the coating.
